So now i want to check whether the OK button is clicked or not.

Confirm could work:

var r=confirm("Click the OK button now!");
if (r==true)
{
  alert("You pressed OK!");
}
else
{
  alert("You pressed Cancel!");
}

Confirm HAS to have an OK and Cancel button. If you only want one button, you should either use the alert() method (which doesn't tell you if the OK was clicked) or you should look into something like the jQueryUI Dialog control.

The jQueryUI dialog is a bit more complicated because you need to include some extra JavaScript libraries and do a bit of extra wiring up to get it to work. There are a lot of examples to follow here.

As mentioned previously, confirm() is the best bet, however don't forget you can check which button was pressed, and ask for a value at the same time using prompt(). 

if (prompt("Click the OK button?")!=null)
{
alert('you clicked OK and entered a value')
}
else
{
alert('you clicked cancel')
}

Use a jquery dialog then you can post or check what every you want from a range of buttons. Much more flexible

Jquery Modal

Sounds like you might want a confirm box instead of an alert:

This returns true or false depending on what the user presses. Alert does not return a value.
